Guava: Google Core Libraries for Java

Guava is a set of core libraries that includes new collection types (such as
multimap and multiset), immutable collections, a graph library, functional
types, an in-memory cache, and APIs/utilities for concurrency, I/O, hashing,
primitives, reflection, string processing, and much more!

Guava comes in two flavors.

The main flavor requires JDK 1.8 or higher.

If you need support for JDK 1.7 or Android, use the Android flavor. You can
find the Android Guava source in the android directory.

IMPORTANT WARNINGS

APIs marked with the @Beta annotation at the class or method level
are subject to change. They can be modified in any way, or even
removed, at any time. If your code is a library itself (i.e. it is
used on the CLASSPATH of users outside your own control), you should
not use beta APIs, unless you repackage them (e.g. using ProGuard).

Deprecated non-beta APIs will be removed two years after the
release in which they are first deprecated. You must fix your
references before this time. If you don't, any manner of breakage
could result (you are not guaranteed a compilation error).

Serialized forms of ALL objects are subject to change unless noted
otherwise. Do not persist these and assume they can be read by a
future version of the library.

Our classes are not designed to protect against a malicious caller.
You should not use them for communication between trusted and
untrusted code.

For the mainline flavor, we unit-test the libraries using only OpenJDK 1.8 on
Linux. Some features, especially in com.google.common.io, may not work
correctly in other environments.

For the Android flavor, our unit tests run on API level 10 (Gingerbread).
